Most Helpful Positive Review Pretty cool upgrade
Bought this thinking it would be kinda difficult. Nope, very easy to work with and adjust. I put it in my .308 and have another in my 556. Haven't shot with it in yet. But I'm sure if it don't work right... I can always adjust it. Only complaint is, that the screw that holds the weights into the buf...

Most Helpful Negative Review Things need to be considered before buying
It's not that I didn't like the product. It's not that it isn't well made. It's not even that it's a bad idea. ODIN Works is one of the best companies in the industry and the concept is sound. There were some problems on my end that have made it, shall we say, not the best choice. Things you need t...

buffer adjustable

by cactuss, Verified Owner from PA, United States Written on October 30, 2026
You are gonna need a scale to weigh the weights,because they arn"t marked. But other than that it saved me money by going adjustable rather than buying different buffers.
Pros:
  • Saves Money
Cons:
  • weights aren't marked
Best Used for:
  • tuning ur ar
Would recommend: Yes

adjustable maybe not permanent.

by J-Rod, Verified Owner from KY, United States Written on October 4, 2026
I have several rifles that I am constantly changing. Instead of having to buy different weights for all of them just to try I bought this for my testing phases. Works out just fine.
Pros:
  • Cheap
  • Adjusability
Cons:
  • Build Quality
Best Used for:
  • testing
Would recommend: Yes

Just the right mass

by Bradizzler, Verified Owner from UT, United States Written on September 24, 2026
This buffer weight is perfect. I use with an FRT in a 16” .556 with a Tubb spring. It makes sure the bolt is all the way in battery when the consumables go boom.
Pros:
  • well built
  • easy set up
  • Good Instructions
Cons:
  • None
Best Used for:
  • AR15 tunning
Would recommend: Yes

Must for AR9s

by Fred, Verified Owner from MS, United States Written on September 22, 2026
Decided to use this to tune my AR 9mm after putting a Franklin Armory binary in it. The muzzle stability on the follow up shot went from about a 4 to a 9!!! What I thought was a failure in posture or recoil mitigation on my part was unequal forces. Everything in balance.
Pros:
  • Tune it for suppersor use
  • tuned
Cons:
  • price
Best Used for:
  • AR Platform
  • Binary fire.
Would recommend: Yes

Odin works adjustable buffer for the win

by yennchi, Verified Owner from SC, United States Written on August 4, 2026
Great buffer! Did the job and good quality! Easy to assemble. Got me to right above a h3 buffer and still have more weight to add if I ever need it.

mainly disappointed in customer service

by chewiez, Verified Owner from MO, United States Written on June 22, 2026
This buffer weight came highly recommended. Seemed like a no brainer honestly makes sense to have an easily adjustable buffer weight. But my problem is with the face of the weight there is what seems to me a pretty aggressive bevel on the face you can clearly see it was sliding forward past the buffer detent scratches on the face all over and this is with literally a brand new Daniel defense m4v7. When I compare it to my stock weight and my geissele h1 the face of the weight is completely flat no bevel on the edge. I would have to pop both front and back pins let the upper slide forward to remove it. I reached out to Odin works literally all they said was I’ve never heard of that and there’s nothing we can do I provided photos and video still they were not interested. Honestly it’s not a super expensive item and I believe I have a solution but they’re lack of willingness to even attempt to help kinda blew me away and is what made this a 2 star

Great Product

by TP11, Verified Owner from TX, United States Written on June 19, 2026
I really liked this producer but wish the heavy version went lower. I suspect that most people need a medium version but are forced to choose between heavy and lite.
Pros:
  • It does everything it says.
  • well built
Cons:
  • not wide enough range of weight
Would recommend: Yes
